The smart thing to do would be to take out your planet before squids become a threat.
Sqid. You're pronouncing the U. Sqid, not squid.
As for a threat. Seriously? We're behind you and getting behinder. Life started on your planet hundreds of millions of years before it started on mine. We don't have beetles! None of our insects can fly!
You want to cause mass extinction on my world? You don't need nukes. Drop down some ant colonies.
Sounds like the hardest part of this project will be NOT destroying them on contact.
An interesting project. I had not expected Sam to think so long term.
It will be years before we will be able to build the probes. About fifty to a hundred years for the probes to reach the likely candidate stars. If successful, another decade or two for us to get the information.
Then someone will need to petition for Sam's people at the bureau of planetary resource allocation. It's here where we can expect our long delays.
